AIRPAX / SENSATA AP121RC62103 Magnetic Circuit Protector

The Airpax AP series magnetic circuit protectors combine power switching and accurate, reliable circuit protection with inverse time delays and trip-free features. Unlike thermal protectors, the AP maintains a consistent trip current across a wide temperature range. Available in various versions (DC, 50/60Hz, or 400Hz) with adjustable delays, these protectors are designed to match specific application requirements. The 'trip-free' action ensures the circuit won't remain closed during an overload, even with the handle in the ON position. Applications include communication, navigation, aircraft instrumentation, radar, and power supplies. The UP series, UL and CSA certified, offers an optional FM approval for petrochemical applications. AP-MIL protectors meet MIL-PRF-39019 standards and undergo rigorous testing for quality assurance.
